Help! Effort calculation

Homework Statement

Calulate the effort required to lift the load?

Homework Equations

Load=1962N Lever of the third order

effort lies inbetween load and pivot(fulcrum)

load is 5m from effort and fulcrum is 1m from effort

The Attempt at a Solution

My attempt at solution.

Distance from load to fulcrum x load = 11772

11772 / distance from fulcrum to effort = 11772

Answer 11772

Mechanical Advantage = 11772 / load 1962 = MA is 6

Is this correct please help!

Hello,

Thank you for reaching out for help with your effort calculation problem. I am happy to assist you in finding the correct solution.

Based on the information provided, it seems like you have correctly identified that the effort required to lift the load is equal to the distance from the fulcrum to the effort multiplied by the load. In this case, the distance from the fulcrum to the effort is 4m (5m - 1m) and the load is 1962N, so the effort would be 4m x 1962N = 7848N.

To check your answer, we can also calculate the mechanical advantage using the formula MA = load/effort. In this case, the load is 1962N and the effort is 7848N, so the MA would be 1962N/7848N = 0.25. This means that for every 0.25 units of effort, the load will move 1 unit. This is consistent with the lever being of the third order, as the mechanical advantage for this type of lever is always less than 1.

I hope this helps clarify the correct solution for your problem. If you have any further questions, please don't hesitate to ask. Good luck with your calculations!
